Using an external volume as a P-VOL to copy data

1. Use Universal Volume Manager to map the external volume (A) to an internal volume (B) of the local storage system. You will use volume (B) as the P-VOL of a copy pair.
2. Check the capacity of internal volume (B) to which external volume (A) is mapped, and select a copy destination volume (C) that has the same or greater capacity than volume (B). You will use copy destination volume (C) as the S-VOL of the copy pair.
3. If the copy destination volume (C) is bigger than volume (B), create a CV that has the same capacity as volume (B). Create the CV using the block value displayed in the Mapped Volumes tab in the Selected External Path Group window.
4. Create the copy pair using volume (B) as the P-VOL and volume (C) as the S-VOL. This configuration makes a copy of external volume (A).
